Final answer:
Option C, (2 x 10) × 7, demonstrates the commutative property of multiplication.
Step-by-step explanation:
The commutative property of multiplication states that changing the order of the numbers being multiplied does not change the product. In this case, we have 2 × 10 × 7. The option that demonstrates the commutative property is (2 x 10) × 7. This is because we first multiply 2 and 10, and then multiply the result by 7, giving us the same product as multiplying 10 and 7 first, and then multiplying the result by 2. Therefore, the correct answer is option C.
